Mixing the two concentrations would give a new concentration which is in between 50 - 60% .
D. 63% cannot be obtained
0.35x + 0.60y = 0.40(x + y) where x = vol. of 35% and y = vol. of 60%
x + y = 20
solve this system of equations
x + y = 20
-0.05x +0.20y = 0
this gives x = 16 and y = 4
so you need 16 L of 35% and 4 L of 60% solution.
SOLUTION
Below is an example of the graph
Hence the answer is Reciprocsl function
Answer: B is your correct answer.
Step-by-step explanation: If she has already made $95.00 from selling jam and made $24.00 from demonstrations you add those together to get $119. Then you subtract $119.00 from $450.00 and you'll have $331.00 left to make. Finally you divide $331.00 by $5.00 (cost of jam) and you'll find that you have to sell 66 more jars of jam.
